Description

Chain Guide Potato Harvester

technical field

The utility model relates to the technical field of potato harvesters suitable for ridge farming in dry farming agricultural areas in Northwest China, in particular to a chain guide rail type potato harvester for full-film double-furrow planting.

Background technique

The development of foreign potato harvesters started early, developed rapidly, and had a high level of technology. It mainly produces large and medium-sized combine harvesters, which are bulky, complex in structure, and relatively expensive, while the development of potato harvesters in my country started relatively late. China is one of the countries with the fastest potato development. The national potato planting area has reached 13.5 million hm ² , most of which are planted in mountainous or hilly gully areas. Harvesting mainly depends on human and animal power. The production efficiency is low and the labor intensity is high, which restricts the development of the potato industry. Further development. It has become the strong wish and market demand of the majority of growers to plant potatoes with film mulch on a large scale in the arid area of Northwest China and realize the mechanization of potato harvest. At present, the separation devices used in existing potato harvesters are generally chain-type, and the chains connecting the rods are on both sides. Due to the large width of the chains, there is separation of soil clods when potatoes are harvested from potatoes planted in full-film double-furrows. Due to problems such as uncleanness and low clear potato rate, the existing chains on both sides of the separation and lifting chain cannot achieve complete separation.

The welding frame is installed on the frame, the left shovel and the right shovel are one piece, the middle shovel is four pieces, the left shovel, the middle shovel and the right shovel are evenly welded on the welding frame, the longitudinal section of the digging device It is in the shape of "~", which improves the ability of entering and crushing soil.

The midpoint of the bar is fixed on the chain, and when the chain rotates, the bar is driven to move in the guide rail mechanism, and the potatoes are shaken, loosened, vibrated and broken on the chain, so as to completely separate the soil clods.

The guide rail mechanism includes a fixed plate, a guide rail and a fixed bolt, and the fixed plate is fixed on the frame by the fixed bolt; when the chain rotates, the rod moves in the guide rail, and the guide rail supports the rod and prevents the rod from swinging up and down.

The beneficial effects of the utility model are: the chain guide rail type potato harvester, the machine can complete two rows of potato excavation, soil and potato separation and other processes at one time, the chain of the separation device is in the middle of the bar, and the two sides of the bar are on the guide rail The separation device plays a role in conveying and completely separating the potatoes, reducing the situation that the potatoes are covered by the soil, and the structure is novel and the rate of clear potatoes is high.
